 After starting up the test app, you can see the list of functional test components on the index page (along with links to the source code):

+## Note on testing with DataMapper/Sequel Support
+To install the test app with DataMapper or Sequel, put ORM=dm or ORM=sq
+into your environment.
+For example to set-up DataMapper support run
+
+    # in test/basepack_test_app
+    ORM=dm bundle install
+
+To run the test app in DataMapper-Mode (will use DataMapper models instead of ActiveRecord models)
+
+    # in test/basepack_test_app
+    ORM=dm rails s
+
+To run the test suite
+
+    # in test/basepack_test_app
+    ORM=dm bundle exec rake
+
+etc.
+
+NOTE: netzke-basepack is not dependant on neither DataMapper nor Sequel.  It will pick the right DataAdapter for your models automatically.
+ActiveRecord is still included in Gemfile of the test app, as netzke-persistance is used which uses ActiveRecord.
+If you don't use netzke-persistence, then you don't need to include ActiveRecord.
+
+## DataMapper support
+DataMapper support is *incomplete*, as I didn't find a good way to sort by an association's column when the association needs a LEFT OUTER JOIN (i.e. nullable foreign key in many_to_one).
+
+## Sequel support
+
+CAVEATS:
+  - you can't use polymorphic associations for the time being, as the sequel_polymorphic plugin is not supported by netzke-basepack
+  - SearchPanel is broken atm. When it's fixed, Sequel support for
+    SearchPanel triggered queries should be implemented.
+
 ## Icons support
 Netzke Basepack can make use of FamFamFam Silk icon set (http://www.famfamfam.com/archive/silk-icons-thats-your-lot/). To enable this, download the icons and put the "icons" folder into your app's public/images folder. Then restart your application.
 
 ## Ext 3 support
 Versions 0.6.x are for you if you're using Ext 3 (*hardly maintained*)
